How to reproduce:
1. Open any project
2. Right click in Project Browser and create two Lighting Settings Assets
3. While one of the Assets is selected, change "Direct Samples" value to 64 in the Inspector
4. Hold Shift or Ctrl and select both of the Assets
5. Select the second Asset and see that the value has changed in the Inspector

Expected result: Different values should be indicated when multiple Lighting Settings Assets are selected with a grey symbol (-)
Actual result: Some Lighting Settings Assets values, e.g. "Direct Samples", "Indirect Samples", "Environment Samples" change to the same value of the other Asset when multiple Lighting Settings Assets are selected with different values

Reproducible with: 2022.1.0a13, 2022.1.12f1, 2022.2.0b3, 2023.1.0a4
Not reproducible with: 2020.3.37f1, 2021.3.7f1, 2022.1.0a12

Reproduced on: Ubuntu 18.04, Windows 11, macOS Monterey

Notes:
1. Some values, like "Minimum Bounces" on the newer versions do not change when multiple Assets are selected, but indication in the difference of values is still not indicated with a grey (-) symbol
2. Other values are not affected at all, e.g. when changing from Progressive CPU to Progressive GPU
